Background: Recent decades have seen a rise in population movements and, therefore, the spread of tropical diseases and changes in the epidemiology of global disease patterns. Only 50% of travelers to tropical areas receive pre-travel advice and most of them present risk behaviors for acquiring infections. The aim of this study was to describe the clinical and epidemiological characteristics of travelers and identify factors associated with risk behaviors.
Methods: We made a retrospective, descriptive and analytical study of 772 travelers consulting a tropical medicine clinic in Barcelona in 2010. Data on demographic and clinical variables, travel characteristics and risk behaviors were collected.
Results: Among all travelers studied, 65.8% (466/708) received pre-travel advice and 30.7% (209/680) took malaria prophylaxis. At least one risk behavior was reported by 82.6% (587/711) of travelers. People traveling for 1-6 months had a 3-fold higher likelihood of experiencing risk behaviors than people traveling for <1 month (95% CI 1.54-5.81, p=0.001), and those traveling for >6 months had a 13-fold higher likelihood (95% CI 3.11-56.14, p<0.001) compared with the same group. Increasing age was associated with presenting less risk behaviors.
Conclusions: Younger travelers and those making longer trips have a higher number of risk behaviors. Strategies emphasizing advice on risk behavior should focus on these groups.

Objective: Posttraumatic stress symptoms (PTSS) and moral injury (MI) are possible negative outcomes of combat military service. While PTSS is known to be associated with impaired paternal parenting, no study has examined the association between MI and parenting. This study examined associations between military-related PTSS, MI, and multiple measures of parenting among veteran fathers.

Objectives: This study aimed to examine the relationship between marijuana use and aggression and victimization among Colombian adolescents. We aimed to clarify marijuana's distinct role by comparing different categories of drug use and by considering the order of drug initiation.
Methods: We conducted a secondary analysis of nationally representative cross-sectional data collected from Colombian adolescents in 2016.
Imprint of ancestral and modern threats in human mind - experience of fear, disgust, and anger.

Introduction: Threats to our survival are often posed by the environment in which humans have evolved or live today. Animal and human ancestors developed complex physiological and behavioral response systems to cope with two types of threats: immediate physical harm from predators or conspecifics, triggering fear, and the risk of infections from parasites and pathogens leading to the evolution of the behavioral immune system (BIS) with disgust as the key emotion. Here we ask whether the BIS has adapted to protect us from pandemic risks or poisoning by modern toxic substances.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

Collective behavior in biological systems emerges from local interactions among individuals, enabling groups to adapt to dynamic environments. Traditional modeling approaches, such as bottom-up and top-down models, have limitations in accurately representing these complex interactions. We propose a novel potential field mechanism that integrates local interactions and environmental influences to explain collective behavior.
